Abstract: An electrochemical cell is described, including an anodic chamber and a cathodic chamber separated by an electrolyte separator tube, all contained within a cell case. The cell also includes an electrically insulating ceramic collar positioned at an opening of the cathodic chamber, and defining an aperture in communication with the opening; along with a cathode current collector assembly; and at least one metallic ring that has a coefficient of thermal expansion (CTE) in the range of about 3 to about 7.5 ppm/° C., contacting at least a portion of a metallic component within the cell, and an adjacent ceramic component. An active braze alloy composition attaches and hermetically seals the ring to the metallic component and the collar. Sodium metal halide batteries that contain this type of cell are also described, along with methods for sealing structures within the cell.

Abstract: The present application provides for ceramic collars and metal rings for active brazing in sodium-based thermal batteries. The ceramic collar may be an alpha-alumina collar configured for active brazing, and thereby sealing, to outer and inner Ni rings for use in NaMx cells. The portions of the alpha-alumina collar active brazed to the outer and inner Ni rings may be outwardly facing and include inwardly extending recesses. The portions of the outer and inner Ni rings active brazed to the outwardly facing portions of the collar may be inwardly facing. The alpha-alumina collar may include a greater coefficient of thermal expansion than each of the outer and inner Ni rings, and the alpha-alumina collar and outer and inner Ni rings may be configured such that a portion of the outer and inner Ni rings is deformed into the inwardly extending recesses of the alpha-alumina collar after active brazing thereof.
